Well, we could take this to the extreme, and allow _every_ object to grow a
join method, where join attempts to cooerce to the same type.

Thus:
" ".join([L"foo", L"bar"]) -> "foo bar"
L" ".join(["foo", "bar"]) -> L"foo bar"
" ".join([1,2]) -> "1 2"
0.join(['1',2']) -> 102
[].join([...]) # exercise for the reader ;-)

etc.

Mark.
